Specification of Letters Patent.

Patented J an. 11, 1916.

Application filed December 14, 1914. Serial No. 877,170.

To all whom it may concern Be it known that I, RAYMOND GIRARDOT, acitizen of the United States, residing at Detroit, county of. Wayne,State of Michigan, have invented a certain new and useful Improvement inSwitch-Locks, and declare the following to be a full, clear, and exactdescription of the same, such as will enable others skilled in the artto which it appertains to make andvv use the same, reference being hadto the accompanying drawings, which form a part of this specification.

This invention relates to switch locks, and has for its object, thelocking of a switch which controls the electric current, that fires thefuel in the cylinders of a gasolene engine.

In the drawings, Figure 1 is a front elevation. Fig. 2 is a sideelevation partly in section. Fig. 3 is a front elevation showing thecover lifted.

It has already been proposed to cover the switch key socket with a coverlocked in place, so that another key or instrument cannot be insertedwhile the automobile, or engine, is left unguarded. However, theprevious devices have been so arranged that the retaining screws werenot protected and anyone could unscrew the device from its base andoperate the switch just as well as if the device had never been put on.Further, my device is so arranged, that the. flanges come down over thesides of the switch, so that it would be almost impossible to insert aninstrument between the cover and switch and pry the cover loose.

A further feature is the provision of room in the cover so as to allowthe switch key to remain in position. This is quite a decided advantage,as it is not necessary to take out the switch key when leaving the carunless it is desired to so do.

a represents the switch casing in which the switching devices arelocated, but inasmuch as switches of this'character are old, the detailsare not illustrated nor will they be described. Sufiice it to say, thatby turning the switch key I) from the central position marked Off in thedrawing, either the battery can be connected with the engine cylindersor the magneto, depending upon the direction in which the switch key ismoved from the central Ofl' position shown in the drawings,movement tothe left switches on the magneto, movement to the right switches on thebattery.

The fixed plate or leaf of the hinge designated c is screwed to the faceof the switch a. It is shown in the drawings as conforming to theoutline of the switch casing and is apertured in the center so as toleave the they cannot be removed whlle the cover 7 1s locked to thefixed leaf or plate a. This locking is effected by passing a. smallpadlock 9 through the perforations of the hasp d of the fixed leaf orplate a and the hasp k on the free end of the cover 7 which registerswith the hasp (i when the cover is closed.

The cover f is provided with a boss '5 which furnishes .space toaccommodate the switch key I) so that when the cover is closed over theswitch casing, it is not necessary to remove the switch key.

Another feature is the provision ofa fiange j on the cover. 'Thls flangecomes down over a portion of the sides of the switch casing so as tomake it well nigh impossible to insert a tool between the two leaves ofthe hinge to pry them apart. The a ends of the hinge-pin are upset sothat the hinge-pin cannot be knocked out.

What I claim is: 1. The combination with a switch casing provided with akey socket, a switch lock comprising an annular plate having a centralaperture therein fitted to the switch casing, fastening means forsecuring said plate 95.

to the casing, a cover hinged to said plate and adapted to swingdownover the same and protect the fastening means and prevent access to thesocket, and means for locking said cover and plate together.

' 2. The combination with a switch casing provided with a key socket, aswitch lockcomprising anapertured plate conforming to the contour of thecasing and having a flange adapted to overlie the sides of the casing,fastening devices for securing said or the cover 65 plate to the face ofthe casing, a movable cover attached to the plate adapted to over liethe fastening devices and prevent access to the key socket, and meansfor locking the movable cover and the plate together.-

3. The combination with a switch casing providedv with a key sockethaving a key therein, a switch lock comprising an annular plate having acentral aperture therein fitted. to the switch casing, fastening meansfor securing said plate to the casing, a cover having a boss thereinhinged to the plate and adapted to swing down over the same to protectthe fastening means and overlie the key, and socket, and means forlocking said cover in closed position.

4. The combination with a switch casing, provided with a key socket, aswitch lock comprising a plate secured to the casing by suitablefastening devices and leaving the key socket within the casing exposed,a cover for preventing access to the socket attached intense and meansfor locking said cover to the plate. 7 5. The combination with a switchcasing having a key socket therein, a switch lockcomprising a plateattached to said casing near the 'socketand adapted to leave the saidkeysocket exposed, fastening devices'for attaching saidplate to thecasing, a cover for preventing access to the socket hinged to sald plateand adapted to swing down over the fastening devices for the plate andinclose the key socket, and means for locking said cover in its closedposition.

In testimony whereof, ll sign this specification in the presence of twowitnesses.

RAYMQND L. GIRARDOT.
